The HFH80 Series Ripeness/Hardness Tester is a handheld
compact penetrometer for fruit firmness and some vegetable
hardness testing, the universally accepted measure of ripeness.
This tester is the growers’ indispensable tool for knowing when to
pick and ship. The HFH80 Series fruit tester measures the force
required to push a plunger tip of specified size into the fruit pulp.
The force reading assists in determining the appropriate picking
time or monitoring fruit softening during storage. Because of the
number of fruit and vegetable varieties, geographical locations and
other variations, the appropriate firmness for harvesting will vary.
User must combine experience and expertise to establish the
firmness value that applies to their specific variety and locale.
